1. 1) a measurement of the size of something in a particular direction, such as the length, width, height, or diameter; 2) the number of coordinates required to locate a point in space

2. 1) a collection of objects or a set; 2) a topological space having specific properties

3. a branch of theoretical physics in which the point-like particles of particle are replaced by one-dimensional objects called strings

4. the antiparticle of the electron, having the same mass but an equal and opposite charge. It is produced in certain decay processes and in pair production, annihilation occurring when it collides with an electron

5. the theory that the origin of the universe was in a cataclysmic explosion in which all the matter of the universe, packed into a small superdense mass, was hurled in all directions

6. the branch of modern geometry in which certain axioms of Euclidean geometry are restated. It introduces fundamental changes into the concept of space

7. 1) an expression that can be assigned any of a set of values; 2) a symbol, esp x, y, or z, representing an unspecified member of a class of objects, numbers, etc

8. the theory of gravitation, developed by Einstein in 1916, extending the special theory of relativity to include acceleration and leading to the conclusion that gravitational forces are equivalent to forces caused by acceleration
